Now that we are kicking back into high gear with the pool, I'm testing and see that my TA is 40. I remember last year I had to add stuff a few times because my TA drifts down. Is there a reason (other than to try to stabilize PH) that low TA is bad? I have a vinyl pool, with a heater that we rarely use.
Also, someone remind me which raises PH and which raises TA (borax or baking soda). I seem to have forgotten everything over the winter!
